I loath using officials as a reason or excuse for a loss. Here's one that could have made a significant difference. A 15 yard penalty assessed to the right team would have meant 1st and 10 from the Cal 35. It ended up 1st and 10 from the WSU 8. A 58 yard swing on the mistake. There were three Cal scoring drives which didn't go for that many yards (19 was the closest.)
